[Index structure: B+ tree and B tree]
(b). B+ tree index structure is said to be an improvement of B
tree index structure. The most important distinction between them
is that data record pointers exist in both internal and leaf nodes
(i.e., blocks) for a B tree whereas only in the leaf nodes for a B+
tree. Explain why this distinction would make B+ tree a more
efficient structure (in terms of index search speed) overall than a
B tree...

Fig. 1 illustrates a red-black tree, where a thick circle
represents a black data-bearing node, a thin circle represents a
red data-bearing node, and a thick rectangle represents a black nil
node. In your work, you have to write black near a black node and
write red near a red node to indicate the colors. Alternatively,
you may use a rectangle to represent a black node, and use a circle
to represent a red node.
- Draw the resulting red-black...

5. Draw the structure of B+ tree index with 3 levels from root to leaves when Index Blocking factor is 3, and the maximum fill factor is 100%. That is, the max number of Keys per Node = 3. Show the structure of each node in the B+ tree with the keys and (block) pointers as specific as possible where 3 keys in the root node are denoted as K-1, Ki, Ki+1.
